Since 1850．the temperature of Earth’s surface has increased about 0.6°C．Scientists predict it may warm much more by the end of this century．Who’s turning up the heat? Well, it seems that we are! Some of this global warming may be natural．However，nearly all scientists now agree that most of it is due to peoples actions．Over the past 150 years, we've added huge amounts of certain gases, especially carbon dioxide（CO2）to the air．These gases can keep heat near Earth's surface，so more carbon dioxide means more heat is kept near Earth's surface．Global warming may change the weather in ways that lead to more severe storms，floods and droughts．
We add carbon dioxide to the air when we burn things, especially fossil fuels．Fossil fuels are energy sources formed from the remains of plants and animals that lived millions of years ago．Coal，oil，and natural gas are all fossil fuels．People in the United States and other countries started bunting large amounts of fossil fuels more than a century ago．The amount d fossil fuels being burned each year has been increasing worldwide．The more we burn，_____________________．
What can we do to help? Nowadays to live a low-carbon life is quite popular in the world． Low-carbon means to reduce the amount of carbon dioxide．Saving energy and reusing are the key words. In fact, even the simplest everyday activities can make our lives low-carbon．

Scientists who study the climate are still arguing about how fast the earth is warming and how much it will warm, but they do agree that the earth is warming and that it will keep warming if we don’t do anything about it.
Scientists agree that the burning of fossil fuels (化石燃料) like oil and coal cause greenhouse gases to escape into the air and that these gases are causing most of the warming. Another cause is deforestation (cutting down trees) . Trees soak up carbon dioxide, one of the greenhouse gases, from the air.
There are already some changes happening because of global warming. Sea level is rising and some animals are already moving to new homes. It’s already too late to stop global warming completely.
If the warming gets worse, as scientists expect, there may be some kinds of plants and animals that is disappearing because they can’t move to new homes. There may be more storms and floods. Sea level may rise so much that people have to move away from the coasts. Some areas may become too dry for farming.
Global warming is a very difficult problem to fix. People are having a hard time agreeing on what to do about it. For example, everyone agrees that wasting energy is a bad thing to do. But some people think that the federal government (联邦政府) should make laws about it, while other people think it should be up to each person or business to decide what to do.
Many states and businesses in the United States are not waiting until the federal government decides what to do. They have already started working on the problem.

| A．The disappearance of plants and animals and the wasting energy. |
| B．The burning of fossil fuels and storms and floods. |

The rising costs of health care have become a problem for many countries in the world. To deal with this problem, it is reported that a big part of the government’s health budge（预算）has been used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor.
Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt（破产）if the patients had taken ways for early prevention. For example, keeping a balanced diet（均衡饮食）, such as not consuming too much animal fat and trying to have enough vegetables and fruits, seems to be quite important.
One very effective and costless way of prevention is regular（定期的）exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better.
In addition, health education plays a key role in improving people’s health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one’s family medical history is an effective way to help keep healthy. Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late.
However, paying more attention to disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.
